Yes, let's say the uncomfortable things.....
Some in higher paid jobs rely on and benefit from the 'hard work' of those in minimum wage jobs, but don't value that contribution, they mock it because it's not financially rewarding, instead they tell those minimum wage workers they're not doing it right (just like you have) they're not bettering themselves in a meaningful way, rather than recognising that both sides rely on each other and have an important role to play in making the whole thing work.
It doesn't take away from how hard someone has worked for their success, that someone else can work just as hard but not be as financially successful, it's how the whole thing needs to work in order for it to well, work at all.
Without the services the minimum wage workers provide, there's many successful people who wouldn't have had the opportunity to reach their success, or to enjoy that success when they do.
The refusal to value those people providing that service is quite small minded imo, very few are successful and then enjoy that success in a bubble without using things like child care, social care, education, retail and hospitality, you know provided by those people who are on minimum wage that apparently aren't hardworking enough or don't sacrifice enough.
